[0002] The cold drawing process is an important production process in steel pipe processing. The cold drawing equipment is mainly a cold drawing machine. The stainless steel seamless steel pipe is a blank steel pipe before cold drawing. One end of the blank steel pipe that needs cold drawing will be hammered flat and pointed so that the blank steel pipe can extend out of the outer die hole of the cold drawing machine, so that the cold drawing trolley can clamp the hammer head for cold drawing. This process is widely used today, especially the chain cold drawing machine.

[0003] During the cold drawing process of the bar by the chain cold drawing machine: the long length of the bar will cause deviation in the center axis of the bar during the continuous cold drawing process, and even the bar will shake, which will affect the processing quality; and the speed of the bar will gradually increase during the sliding of the guide plate, that is, the dynamic potential energy will gradually increase.

[0007] Preferably, the material guide assembly includes a horizontal column, a blanking guide plate and a torsion spring. The horizontal column is fixedly installed between the machine head and the transmission seat and is arranged parallel to the transmission direction of the chain of the cold drawing machine body. A plurality of evenly distributed blanking guide plates are rotatably installed on the horizontal column. The other side of the blanking guide plate extends to above the rear edge of the blanking frame. A torsion spring is sleeved on the horizontal column, and the two movable ends of the torsion spring are respectively fixedly connected to the side of the blanking guide plate and the horizontal column.

[0008] Preferably, a mounting seat is fixedly connected to the top of the movable clamping table, and a laser rangefinder is fixedly installed on the top of the mounting seat, and the laser rangefinder faces the machine head.

[0010] Preferably, a PLC controller is installed on the transmission seat, and the laser rangefinder and the servo motor are electrically connected to the PLC controller.

[0013] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0014] (I) In the present application, the laser rangefinder can measure the distance from the mobile clamping table to the machine head, thereby ensuring the consistency of the processing length of the bar each time. The lifting roller can provide a guiding support function for the bar during the processing process to prevent the bar from being suspended and shaking or offset. The distances from the two sets of lifting rollers to the machine head are different. When the mobile clamping table moves to the right and passes through the first set of lifting rollers, the laser rangefinder measures the distance value and transmits the signal to the PLC controller. The PLC controller controls the first servo motor to start, so that it drives the first alignment gear to rotate. Under the meshing transmission between it and the second alignment gear, the swing shaft drives the extension arm and the roller body to rotate ninety degrees, that is, the roller body extends to the bottom of the bar and is located on the left side of the mobile clamping table. The guiding support of the roller body for the bar will not interfere with the movement of the mobile clamping table. Similarly, when the mobile clamping table passes through the second set of lifting rollers, the second roller body swings to the bottom of the bar and automatically provides guidance and support according to the processing length of the bar, which is conducive to the smooth progress of the processing.

[0015] (ii) In the present application, after the bar is processed, it will slide along the roller body to the blanking guide plate. The torsion spring on the blanking guide plate can relieve the impact, so that the bar will roll along the blanking guide plate into the blanking frame. When the bar rolls onto the buffer strip in the blanking frame, it will achieve a good buffering effect under the resistance of the non-Newtonian fluid, which ensures the smooth blanking of the bar on the one hand and the safety of the operator on the other.

[0016] (III) In the present application, when the rod material falls onto the buffer strip, under the action of its gravity, the buffer strip will squeeze the reciprocating slide rod, causing the thrust plug to slowly squeeze the non-Newtonian fluid in the liquid storage chamber, and then the buffer strip gradually moves toward the liquid storage chamber, allowing the rod material in the receiving port to slowly fall, bringing convenience to the subsequent staff in collecting materials.

[0036] Specifically, two symmetrically arranged rotating shafts 403 are rotatably installed on the top of the mobile clamping platform 4, and a clamping head 404 is fixedly installed on the two rotating shafts 403, a positioning slide rail 406 is fixedly installed on the top of the mobile clamping platform 4, and a driving gear rod 407 is slidably installed on the positioning slide rail 406, a linkage gear 405 is fixedly installed on the two rotating shafts 403, and the two linkage gears 405 are respectively meshed with teeth on both sides of the driving gear rod 407, an electric push rod 408 is fixedly installed on the mobile clamping platform 4, and the output end of the electric push rod 408 is fixedly connected to the right end of the driving gear rod 407, and the rotation directions of the two clamping heads 404 are opposite.

[0037] Specifically, two upper and lower wheel brackets 201 are fixedly installed on the machine head 2, and guide rollers 202 are rotatably installed on the two wheel brackets 201. The midpoint of the line between the two guide rollers 202 is coaxially arranged with the center of the mold hole on the machine head 2.

[0038] The specific implementation of this embodiment is as follows: the bar material to be processed passes between the two guide rollers 202 and through the die hole on the machine head 2, and the electric push rod 408 works to push the driving gear rod 407 to move, and under the meshing transmission action with the linkage gear 405, the two rotating shafts 403 rotate, and the rotation directions are opposite, that is, the two clamping heads 404 swing towards each other to clamp the right end of the bar material, and the chain on the chain cold drawing machine drives the mobile clamping table 4 to move to the right, and then the bar material is pulled to the right to achieve processing;

[0039] The laser rangefinder 402 can measure the distance from the mobile clamping table 4 to the machine head 2, thereby ensuring the consistency of the length of the bar material processed each time. The lifting roller 6 can provide a guiding support function for the bar material during the processing process to prevent the bar material from shaking or deflecting due to hanging in the air. The distances from the two sets of lifting rollers 6 to the machine head 2 are different. When the mobile clamping table 4 moves to the right and passes through the first set of lifting rollers 6, the laser rangefinder 402 measures the distance value and transmits the signal to the PLC controller 7.

[0040] After the bar material is processed, it will slide along the roller body 603 to the blanking guide plate 506. The torsion spring 507 on the blanking guide plate 506 can relieve the impact, so that the bar material will roll into the blanking frame 5 along the blanking guide plate 506. When the bar material rolls onto the buffer strip 501 in the blanking frame 5, under the resistance of the non-Newtonian fluid, a good buffering effect is achieved, which ensures the smooth blanking of the bar material on the one hand, and the safety of the operator on the other hand.

[0041] When the rod material falls onto the buffer strip 501, under the action of its gravity, the buffer strip 501 will squeeze the reciprocating slide rod 503, so that the thrust plug 504 slowly squeezes the non-Newtonian fluid in the liquid storage chamber 502, and then the buffer strip 501 gradually moves toward the liquid storage chamber, so that the rod material in the receiving port can slowly fall, which brings convenience to the subsequent staff to collect materials.
